The Common Industrial Protocol (Ciptm) THE COMMON INDUSTRIAL PROTOCOL (CIPTM) 1 PUB00122R2 MARCH 2016 ODVA’s four best-in-class networks — EtherNet/IP™, DeviceNet™, ControlNet™ and CompoNet™ — all are linked by one of industrial automation’s most versatile protocols: the Common Industrial Protocol, known as CIP™. CIP encompasses a comprehensive suite of messages and services for the collection of industrial automation applications — control, safety, energy, synchronization & motion, information and network management. CIP allows users to integrate these applications with enterprise-level Ethernet networks and the Internet. Supported by hundreds of vendors around the world and truly media-independent, CIP provides users with a unified communication architecture throughout the industrial enterprise. CIP allows users to benefit today from the many advantages of open networks and protects their existing automation investments, while providing an extensible and upgradeable communication architecture. CIP Networks at a Glance With media independence comes choice — the ability to Hardware options are also offered for applications choose the CIP Network best suited for your application. requiring intrinsically safe hardware.

ControlNet offers a choice of topology options including trunkline-dropline, star or tree. 2 Comprehensive Application The Technical Approach to CIP Coverage in a Single Protocol CIP is a media independent protocol using a producer- consumer communication model, and is a strictly object Functional Safety oriented protocol at the upper layers. Each CIP object Safety application coverage in CIP provides the ability has attributes (data), services (commands), connections, to mix safety devices and standard devices on the same and behaviors (relationship between attribute values and network or wire for seamless integration and increased services). CIP includes an extensive object library to support flexibility. CIP Safety™ provides fail-safe communication general purpose network communications, network between nodes such as safety I/O blocks, safety interlock services such as file transfer, and typical automation switches, safety light curtains and safety PLCs in safety functions such as analog and digital input/output devices, applications up to Safety Integrity Level (SIL) 3 according to HMI, motion control, and position feedback. To provide IEC 61508 standards. CIP Safety has also been adopted by interoperability, the same object (or group of objects) Sercos International. implemented in two or more devices behaves identically from device to device. A grouping of objects used in a Energy Optimization device is referred to as that device’s “Object Model.” The CIP Energy™ provides a family of objects and services Object Model in CIP is based on the producer-consumer for the optimization of energy usage (OEU™) and allows communication model, which can provide more efficient use scalable implementation in the device, from basic energy of network resources than a source-destination model by awareness to advanced functions for controlling energy, allowing the exchange of application information between aggregation and reporting of energy information or dynamic a sending device (e.g., the producer) and many receiving demand-response. Further, CIP Energy allows systems devices (e.g., the consumers) without requiring data to be to monitor energy usage and manage energy for efficient transmitted multiple times by a single source to multiple consumption through dynamic control of energy state and destinations. In order to provide further interoperability in analysis of energy information. Protocol-neutral energy CIP Networks comprised of devices from multiple vendors, attributes provide flexibility in the propagation of energy CIP defines a standard grouping of objects as “Device information via multiple protocols to facilitate e-business Profiles.” In addition to the set of objects implemented in models such as capturing energy requirements as a line the device, Device Profiles specify configuration options item on production bills of material or to implement demand- and I/O data formats. Devices that implement one of response mechanisms for dynamic energy transactions. the standard Device Profiles will respond to all the same commands and will have the same network behavior as Synchronization other devices that follow that same profile. CIP also can Synchronization services in CIP provide the increased provide simple integration of Modbus® devices through use control coordination needed in applications where of its native Modbus translation services. absolute time synchronization is vital to achieve real- time synchronization of distributed intelligent devices and systems. CIP Sync™ is compliant with the IEEE-1588™ standard and allows synchronization accuracy between two devices of less than 100 nanoseconds. Real-time synchronization is achievable over conventional 100Mbps Ethernet systems with a switch-based architecture. Distributed Motion Control Motion application coverage in CIP eliminates the need for purpose-built motion-optimized networks by allowing high performance motion control and other devices to be combined on a single EtherNet/IP network. This results in a modular and streamlined approach to system design and lowers overall system and training cost. CIP Motion™ achieves real-time deterministic behavior of multiple axes through a common sense of time, allowing 100 axes to be coordinated with a 1 millisecond network update to all axes. Clock synchronization between axes of fewer than 100 CIP Network (EtherNet/IPTM, DeviceNetTM, ControlNetTM, CompoNetTM) nanoseconds can be readily achieved, meeting the needs of the most demanding motion control applications.

  • Real-Time Ethernet – PROFINET Technology
    July 2011 Real-Time EtherNet – PROFINET Technology Author: Advantech E-mail: [email protected] www.advantech.com July 2011 Twenty years ago, there were competing network protocols in the enterprise (office) network space. Today, no one would believe that, because there is only one network protocol that is used in 99%-plus of all enterprise networks. That network is Ethernet running TCP/IP. Figure 1 – Ethernet is ubiquitous in the enterprise WHAT IS ETHERNET? Ethernet is ubiquitous. Our computer networks all are run on Ethernet, even our video games and HD video devices in our homes are Ethernet enabled. So it is very important to understand what Ethernet is, how it works, and what it can and cannot do. This is especially important in the industrial environment, as Ethernet becomes common on the plant floor. Ethernet is a family of frame-based, or data packet based, networking technologies that are part of the IEEE 802.3 standard. There are several varieties of Ethernet. Originally based on a coaxial cable format, like the old analog cable TV cable, Ethernet cabling became based on twisted pair technology adapted from telephony (see Fig. 1), because this kind of cable was already run in many offices and was understandable to most cable installers. Thus, 10Base-T was developed as a star topology, similar to telephony, and this was continued in 100Base-T and other higher throughput formats. Ethernet networks consist of nodes, switches, routers and repeaters. Switches, especially smart managed switches, have made it possible to have Ethernet networks consisting of a nearly infinite number of nodes.
